I would not normally stop to answer this question, mainly because

there is no question asked. It's just three statements.

I do have to stop here and leave a remark, however.

Math and Physics are closely enough related that I would not

have expected to see what I see here. Although the math in

this question is reasonable, the Physics is inexcusable.

A rainbow is always a part of a circle.

Rainbows are never parabolas.

You could never cut a parabola out of paper, and then

hold it up in front of you after a rainstorm, and match it

to the rainbow.
